Suppose a jar contains 13 red marbles and 11 blue marbles. If you reach in the jar and pull out 2 marbles at random at the same time, find the probability that both are red.

Consider this expression and the steps to evaluate it. 4^5(−2)^9/4^8(−2)^3 1. apply the quotient of powers:      (−2)^a/4^b 2. evaluate powers:           c/d select the value of each variable. a = _ b = _ c = _ d = _
